The group of nine friends, Mobin, Ali, Amin, Arian, Anahita, Saber, MohammadMehdi, MohammadHossein, and Amir, had gathered at their mansion on a small island for a weekend getaway. But the typhoon that struck had left them stranded for two days. As they sat down for dinner, a mysterious letter with the wax seal of a one-winged eagle appeared on the table. It was from an unknown witch called Beatrice, who claimed that she was going to kill them all before the typhoon passed. At first, they all laughed it off as a prank. But then, they started dying off one by one. The first victim was Mobin, who was found dead in his room with no visible cause of death. Next was Ali, who was found in the library with a dagger in his chest. Amin, the Iranian nationalist, was found drowned in the bathtub. Arian and Anahita were found in their room with their throats slit. Saber, Mobin's old friend and rival, was found in the kitchen with a chef's knife in his back. MohammadMehdi, Amin's rival and friend, was found decapitated in the dining room. MohammadHossein was found in the game room with a pool cue in his eye. The only one left was Amir, who was found dead in the study with a gunshot wound to the head. The culprit claimed to be the mysterious witch, Beatrice. As only they were on the island, it made sense. But as perfect examination of corpses weren't available, even the victims could be the culprit. Furthermore, all the victims died under seemingly impossible circumstances, within locked rooms. It was clear that someone had a motive, but who was it? The story ends with all of them dead. The last sentence in the story is: "When the seagulls cried, none were left alive." It is up to the reader to decide who the culprit truly was. Was it really the witch, Beatrice? Or was it one of the friends, driven to madness by being stuck on the island for so long? The answer will remain a mystery, just like the deaths of the nine friends.
